E881 Mapmanager Files

There are nine map files in E881:

align_map

This contains the run-by-run alignment parameters, and is automatically updated whenever an alignment run is analyzed.

alignsum_map

This contains the run-by-run alignment sums, which are used to compute alignment parameters. This is updated for each run, but does not affect anything unless used to generate new entries in align_map.

drift_map

This contains the plane and shift-register drift parameters (Vd and T0) for each run. These are updated at the end of each run if any of them were found to have changed.

driftsum_map

This contains the drift sums, which are used to compute drift parameters in drift_map. This is always updated at the end of a run.

hists_map

This contains the histograms, histogram definitions, scatterplots and scatterplot definitions of each histogram and scatterplot specified in the file "hists_par" with the "M" (Monitor) option. "hists_par" is the standard MPS histogram/scatterplot parameter-file.

hot_map

This contains the hot-wire parameters for each run. These are updated at the end of each run if any of them were found to have changed.

hotsum_map

This contains the hot-wire sums, which are used to compute hot-wire parameters in hot_map. This is always updated at the end of a run.

runinfo_map

This is the general run-description database containing, among other things, each run's "type", which describes the type of data in a run and which is set from the ASCII file runinfo_par when the MAINDI command "run update" is issued. It also contains various "run summary" items, typical of the sort of thing found in an end-of-run output file.

scalers_map

This contains all of the scaler and trigger end-run totals, as well as spill-scalers which are declared with the "Monitor" option in the scaler definition file scalers_par. The triggers are defined in the file triggers_par.
